Is there any way (application, site, API) to see that a friend is online? Run the client of the game and check every 10-20 minutes friendlist is not always possible (takes too much computer resources). In addition, a friend login into the game not every day, and there are no other ways to contact him.
From wiki. "Friends: a list of all the player's contacts showing status, character name, location, and achievement points. Displays additional information for other players that also have you on their friends list". Is there any way to find out when a friend was online last time, how is it done in the guild information? "Additional information" is just level and class of logged character.
I do not know which forum category this topic belongs to. Question about the API, so I created a discussion in this category
